Display Shuts Off During CallsRead the post you referred me to and I had seen that before, hence my list of actions taken to date. However, I did miss mentioning that I also tried dialing *#36# as per several suggestions and received the following responses "USSD code running..." followed by "Connection problem or invalid MMI code" Am I doing something incorrectly?

When making calls the screen turns offTried the *#36# proposed solution by dialing that sequence as per a normal call and received the following response "USSD code running..." followed by: "Connection problem or invaild MMI code." Any other suggestions?
